Abstract
Polycrystalline copper with a (112)[1\bar10] orientation was cold-rolled up to 85 pct and the slip rotations toward the stable end position was studied.
The normal to the rolling plane rotates toward [\bar111] and the rolling direction toward [101]. After rolling of 85 pct, the rolling plane normal arrives at the vicinity of [\bar123] without passing [011] and the rolling direction approaches [2\bar11]. Then the pure metal type texture containing (\bar112)[1\bar11] as a minor component is developed. These slip rotations can be well explained as due to the operation of slip systems bearing the highest resolved shear stress and their cross slip systems. So, the minor component is considered to be described as an orientation near (\bar112)[2\bar11] rather than (\bar112)[1\bar11], since it is necessary that slip systems taking the rolling direction toward [1\bar11] must operate extensively to cause the orientation near (\bar112)[2\bar11] to displace to (\bar112)[1\bar11]. In consequence, the results obtained in the present work are not consistent with the theory of Dillamore et al. which proposed the pattern {011}⟨211⟩→{123}⟨211⟩→{112}⟨111⟩.
